MACHINE FOR CUTTING METAL ROLLS.

Application filed February 5, 1910.

To all whom it may concern:

Be it known that I, GoT'rFRn) KNAUS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Cutting Metal Rolls, of which the following is a specification.

My invention relates to a machine for cutting'metal rolls or collars used, for example, in rolling tie plates.

A primary object of the invention is to provide, for use in connection with a machine designed to cut or otherwise operate upon an object formed with a central circular opening, such, for example, as the steel collar forming a part of the composite roll shown in the application of David H. Lentz, filed December 4:, 1909, Serial No. 531,471, a suitable holding device for said object or collar upon which the same is rotatably mounted, so that when, in the particular case specified, one cut or groove is finished the collar may be turned to present a new portion of the surface thereof to the cutting tool, the supporting device being provided with clamping means whereby the collar may be clamped thereon while the cuts are being made; the purpose of this supporting device, which will be hereinafter more particularly described, being to facilitate the resetting of the collar before each cut is made and to insure placing the cuts with perfect accuracy on the perimeter of the collar.

The invention has for further objects such other new and improved arrangements, constructions and devices relating to machines for cutting, planing and otherwise finishing the rolling surface of metal rolls, as will be described and claimed herein.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein Figure 1 is a front elevation of the machine, the forward part of the base being shown in section. Fig. 2 a side view partly in section looking from the left of Fig. 1. Fig. 3 a sectional plan taken on line 3-3 of Fig. 1. Fig. 4 a plan view of the cutting mechanism. Fig. 5 a central vertical section through the collar supporting device. Fig. 6 a view in perspective of the bottom of a tie plate which the roll shown in the other figures is designed to form. Fig. 7 is a Vertical section showing the adjustment Specification of Letters Patent.

between certain parts of the cutting mechanism.

Like characters of reference indicate like parts in the several figures of thedrawings.

Referring to the drawings, 10 represents the base of the machine which may be of any desired construction and which is preferably formed with the grooved ways 11 on which is slidably mounted the carriage 12. The carriage may be reciprocated by any desired form of driving means. For example, a rack 13 may be provided on the under side of the carriage with which meshes one or more driving pinions 14:.

The collar 15, which the machine opcrates upon, is supported on the carriage 12. The supporting means for the roll consist-s preferably of a standard or upright plate 10 which has the base 17 and strengthening webs 18, 18, to which is secured a cylindrical block 19. I have shown the block as formed with the central stud 20 which projects through an opening in the standard 16, which at this point is reinforced by the boss 21, the end of the stud being threaded for the nut 22. The block may be additionally secured to the standard by the bolts 23. In order that the collar support may be placed in any desired position on the carriage 12, the latter is formed with the slots 24 having the enlargements 25 which receive the heads 26 of bolts 27, which extend through the clamps 28 and are provided with nuts 29, the clamps overlapping the base plate 17 of the collar support. It is obvious that other means might be employed for adjustably securing the collar support to the carriage.

In practice the perimeter of block 19 is accurately formed, as is likewise the inner surface of the collar on which the machine is to operate. A good fit is made between the collar and the block, but such as to allow the collar to be turned. Before a cutis made the collar is firmly clamped on the support. To this end the block 19 is formed with threaded bores for the clamping screws 30 which bind the angular clamps 31 against the block and against the side of the collar, blocks 32 being interposed, ifv necessary, between the clamps and the collar. Any other means might be employed for holding the collar from rotation on the cylindrical block 19. When any particular cut on the perimeter of the collar has been made the clamps may be loosened and the collar surface of the collar, the collar support as a whole will be set at the proper angle for making one series of cuts and will not need to be reset until the whole series has been cut, after which it will be readjusted at the proper angle for making the other series. It will follow that if the parts are properly constructed, accurate parallelism between the cuts of each series will be maintained. Thus after the particular adjustment of the collar support for one series of cuts is made the work of making the cuts may be carried on by unskilled labor, as, after each cut is made, it is necessary only to loosen up the clamps, fix the position of the new cut by a gage, tighten the clamps again and proceed with the next succeeding cut.

The cutting is done by a tool 33 held in a tool holder 34 by means of a set screw 35. The tool holder is secured to a block 36 which is mounted by means of a, pin 37 in a forked plate 38, which has the curved slot 39, through which extends a set screw 40, by means of which the plate 38 may be bolted, so as to hold the cutting tool in a position oblique to the vertical, if desired, to a slide 41 which has a dove-tailed slot which fits the dove-tailed guide 42 on the circular block 43. The block 43 is secured by means of the set screws 44 to a slide 45 having the dove-tailed part 46 guided in a correspondingly formed slot in a circular projection 47 on the horizontally sliding head 48. The guide 42 has the threaded perforation 49 for the adjusting screw 50, the upper end of which is smooth and extends through a lug 51 on the slide 41, the screw being formed with the collars 52, one on each side of lug 51 and with the square end 53 by means of which it may be turned with a wrench. Any other means might be employed for obtain ing a convenient vertical adjustment of the tool 33.

The head 48 slides upon a transverse bar 54 which is supported from the base 10 by the vertical supports 55. Preferably, the head 48 is formed with the lugs 56 which are threaded for the worm shaft 57, mounted so as to turn in a recess 58 in the bar 56. If desired, the worm shaft may have the crank 59so that it can be turned by hand to give a horizontal shift to the head 48. WVhen the machine is organized and operated in the manner shown, the horizontal shifting of the head is merely'for the purpose of initial adjustment,

The cuts on the rolling surface of the collar run diagonally thereof, and as a consequence the cutting tool rises and falls as each cut is being made. This vertical movement of the tool is made possible by the sliding engagement between the slide 45 and the head 48. It is determined by a templet 60 which is bolted to a standard 61 having the base plate 62, which may conveniently be clamped to the carriage 12 by means of clamps 28 of the same character as those by means of which the collar support is secured to the carriage. Obviously, any other means might be employed for mounting the templet on the carriage. The templet is engaged by a follower 63 which is secured to the under side of the slide 45. The slide 45 is formed with the flange 64 having staples 65, on the under side thereof engaged by the ends respectively of the coiled springs 66, the other ends of these springs being hooked into staples 67 on the brackets 68, secured to the circular projection 47 of the head 48.

The operation of the machine, as above described, is as follows: The collar support is first adjusted at the proper angle on the carriage 12 by means of the clamps 28. The collar is then clamped on the support by means of the angular clamps 31. A tool 33 of proper shape for making the cut is placed in the tool holder in such position that it will come in contact with the roll when the carriage is reciprocated, and a templet 60 of a configuration determined by the character of the cut to be made on the roll is fixed to the standard 61, and this device clamped in proper position on the carriage. When the carriage is reciprocated the forward stroke, that is the movement from right to left as the machine is shown in Fig. 2, will bring the roll into contact with the tool 33 in a line running diagonally of the perimeter of the roll. The tool 33 with this movement of the carriage is held to its work because the block 36 is forced against the plate 38. When the carriage is moved in the opposite direction the block 36 is rocked outwardly on its pivot 37 so that the tool willsimply ride over the collar. As the cut becomes deeper it is necessary to adjust the tool downwardly and this is conveniently done by turning the adjusting screw 50. It will be seen that the tool must rise and fall with each cut,'the curve described by the tool on the surface of the roll being depend ent on the angularity of the cut and the radius of the roll. This curve is worked out and the templet 60 is formed in accordance therewith. As the carriage is moved back and forth the templet comes into contact with the follower 63 and forces the slide 45 upwardly against the tension of the coiled springs 66.

figures.

WVhen one series of parallel cuts have been made the angular position of the roll support is shifted and the other series of cuts are made in a similar manner. In the drawings the cuts 69 are supposed to have been made with the roll in a position the reverse of that shown, the machine being shown as making the successive cuts 7 O of the other series.

It will be seen that having once adjusted the collar support to its proper position on the carriage and having made a proper adjustment of the other parts of the machine, each of the successive parallel cuts may be made by simply shifting the position of the collar on block 19, measuring off the starting point of each new out with a gage or measure.

In order to better illustrate the use of the machine I have shown in Fig. 6 the lower surface of a tie plate 71 which is formed by a roll of the character shown in the other The ribs 72 on the plate are formed by the cuts or grooves 69 and 70 on the perimeter of the roll.

As modifications of the machine, as shown, will readily suggest themselves to those skilled in the art, I do not limit myself to the particular devices, constructions and arrangements shown and described except as required by the scope of the appended claims. While the means for supporting the collar is shown in connection with cutting apparatus which operates diagonally of the perimeter of the collar, it will be obvious that such supporting means might be used with apparatus which operates in a different manner on the object supported.

I do not claim specifically the form of cutting mechanism herein shown as the same was made the subject matter of my application Serial No. 592,310, filed November 14;, 1910, which is a division hereof.

I claim:

1.
